Benefits of technology

[0131] An advantage of the present invention relates to the improved ability to treat pain in a variety of patients with a simpler formulation or composition than the non-monoeximic and complex dosage forms described in Example 4 of Cruz et al. Pain management often involves a combination of a chronic pain medication with a rescue medication.
[0132] The sustained release monoeximic dosage forms and pharmaceutical compositions of the present invention provide a means for producing or providing the following plasma profiles in human patients. Any and all of these pharmacokinetic parameters are expressly encompassed within the scope of the invention and the appended claims.
[0133] Specifically, when administered to a human patient, in certain embodiments, the dosage form or pharmaceutical composition produces the blood plasma concentration profiles described above.
[0134] It is to be understood that while the invention has been described in conjunction with the preferred specific embodiments thereof, that the description above as well as the examples that follow are intended to illustrate and not limit the scope of the invention. The practice of the present invention will employ, unless otherwise indicated, conventional techniques of organic chemistry, polymer chemistry, pharmaceutical formulations, and the like, which are within the skill of the art. Other aspects, advantages and modifications within the scope of the invention will be apparent to those skilled in the art to which the invention pertains. Such techniques are explained fully in the literature.

Problems solved by technology

These systems generally require complicated manufacturing processes that can be inefficient, expensive or both.

example 1

Preparation of Extended Release Monoeximic Dosage Forms Containing Acetaminophen (APAP) and Hydrocodone Bitartrate Hemipentahydrate (HBH) at Lab Scale

[0135] This example shows the preparation of single unit monoeximic matrix dosage forms.

[0136] Tablets weighing about 800 mg were prepared using wet granulation using a laboratory high shear mixer (Key International Inc.). APAP dense powder was dry mixed with HBH, and excipents except for APAP DC-90, silicon dioxide and magnesium stearate for 1.0 minute (150 rpm) followed by granulating with Eudragit L-30D aqueous dispersion at low speed (200 rpm) for approximately 2.0 minutes in the high shear mixer. The wet granules were then dried in an oven at 50° C. overnight and passed through a 20-mesh screen. The granulation was blended with APAP DC-90 and silicon dioxide for 3.0 minutes, and magnesium stearate for an additional 2.0 minutes at 25 rpm in a V-blender. The powder blend was subsequently compressed into tablets using a hydraulic C...

example 2

Preparation of Sustained Release Monoeximic Dosage Forms Containing APAP and HBH at Lab Scale

[0139] This following example shows the preparation of multi-unit monoeximic matrix dosage forms.

[0140] Tablets weighing 192-200 mg were each prepared using wet granulation or direct compression. For wet granulation, APAP dense powder was dry mixed with HBH, lactose and proportional amount of hydroxypropyl methylcellulose (HPMC) (listed in Table 3 below as Methocel K100LV and Methocel K4M) for 2-3 minutes (150 rpm) followed by granulation with an Eudragit L-30D aqueous dispersion at low speed (200 rpm) for approximately 2 minutes in a laboratory high shear mixer (Key International Inc.). The wet granules were then dried in an oven at 50° C. overnight and passed through a 20-mesh screen. The granulation was blended with other excipients including the remainder of HPMC, hydroxylpropyl cellulose (HPC) (listed in Table 3 below as Kluecel EXF), APAP DC-90 and silicon dioxide for 3 minutes and t...

example 3

Preparation of Extended Release Monoeximic Dosage Forms Containing APAP and HBH at Pilot Plant Scale

[0144] This example shows (1) multi-unit monoeximic matrix dosage forms designed for bioavailibility evaluations in humans; and (2) the resistance of the monoeximic matrix dosage forms to dose dumping from these dosage forms after the consumption of alcoholic beverages.

[0145] The dosage form used in this Example to evaluate human biovailability and that used to assess the impact of alchoholic solutions on the dosage forms differed from each other by 1% Eudragit L-30D-55 by weight.

[0146] Three (3) formulations that were designed for the bioavailability study in healthy subjects are provided in Table 5 below. Tablets weighing about 192.5-200 mg each were prepared using wet granulation. APAP dense powder was dry mixed with HBH, lactose (for Formulation F only) and approximately 8% hydroxypropyl methylcellulose (HPMC, Methocel K100 LV for Formulations F and T, Methocel K4M for Formulat...

Abstract

The present invention relates to SRSR solid dosage forms for administering pharmaceutical agents, particularly Hydrocodone and acetaminophen, methods for preparing said dosage forms, and methods for providing therapeutic agents to patients in need of treatment.

Description

[0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 949,141, which is incorporated by reference in this application in its entirety. In addition, all patents, patent applications and literature references cited in the specification are also incorporated by reference in their entirety. In the case of any inconsistency, the present disclosure, including definitions, will prevail.FIELD OF THE INVENTION [0002] The present invention provides monoeximic solid dosage forms for administering pharmaceutical agents, methods for preparing said dosage forms and methods for providing therapeutic agents to patients in need of treatment thereof. BACKGROUND OF THE INVENTION [0003] Extended release of acetaminophen (“APAP”, paracetamol) and hydrocodone (“HC”) that can be administered twice a day (BID dosing) has previously been achieved using osmotic systems, two release-component matrix systems and two release-component coated reservoir systems as disclosed in U...
